What is weathering
breaking down of rocks and minerals, on earth's surface
What is a mid ocean ridge
new ocean floor created as tectonic plates shift
What is continental crust? Where are they found?
layer of rocks that makes up land and forms continents ( found in 7 major continents)
Which two pieces of evidence support the claim that the continents were once joined.
same fossils were found on each continent (Glossopteris plant) and they fit like a puzzle piece
Which of the following is most likely to occur at a transform plate boundary?
floods
earthquakes
What is erosion
water/ wind/ natural forces cause earth to wear away
What is an oceanic oceanic divergent boundary
2 ocean plates move apart/ new oceanic crust is filled in the open space as plates move
Who came up with the Pangea theory? What was his theory?
Alfred Wegener (all continents once fit like a puzzle and were one major piece of land)
When plates move together, they form what?
mountain range
Where does the Earth's internal heat source come from?
Core
What is meteorology and what is a meteorologist
study of climate and weather
someone who studies/ predicts the climate/ weather
What is an oceanic oceanic convergent boundary
2 ocean plates collide, the denser one sinks under the less dense plate
What are continental continental divergent boundaries
new oceans are created in open space as continents break apart/ move away
What was the name of the super continent
Pangea
A mid-ocean ridge is an example of what type of plate boundary?
Divergent
What is dual polarization
horizontal/ vertical pulses used as a way to understand why certain weather occurs
What is convection
movement of energy as a result of heat
What are continental continental convergent boundaries?
2 continental plates collide and form mountains, earthquakes and volcanoes
Describe climate
long-term pattern of weather in a particular area
Which of the following statements provides evidence for the theory of plate tectonics?
All of the above
What are some ways to predict weather
Observe recent weather patterns
Look at geography (In the wintertime, it rarely snows in Arizona, so that won’t be very common)
Temperature, air pressure, humidity, cloudiness, and wind affect the weather, so these are monitored closely and regularly
What is oceanic crust? Where are they found?
crust that makes up the sea floor
found on major ocean floors
What is continental continental subduction?
continents dip under each other causing friction (volcanoes can form)/ earthquakes/ lighter plate on top, dense one on bottom
Look at the picture. Describe whether the Nazca plate is oceanic or continental. Describe whether the South American plate is oceanic or continental. In order to form a mountain range, will these plates converge or diverge?
https://en.wikipedia.org/wiki/Chile_Ridge#/media/File:Americas_Tectonic_Plate_Map_-_by_NOAA.jpg
Nazca- oceanic
SA- continental
converge
The theory that describes the formation, movements, and interactions of these plates is called?
Plate tectonics theory
